This chapter follows human reproduction from the organs that make gametes, through the formation of sperm and ova, the monthly cycle in females, fertilisation and implantation, to pregnancy, birth and milk production. It builds on the cell division you studied in Class 11 and sets up the next chapter on reproductive health.
